smp_utils-0.91 available

smp_utils is a package of command line utilities for invoking SMP functions to monitor and manage SAS expanders. SMP is the Serial Attached SCSI (SAS) Management Protocol (SMP). A SAS Host Bus Adapter (HBA) includes a SMP initiator (along with a SSP and STP initiator). A SAS expander contains a SMP target. Several SAS HBAs have a SMP pass through interface that can be used to send SMP requests and receive the responses. This package targets the linux kernel (lk) 2.6 and lk 2.4 series.

Two interfaces are available: the "mptctl" pass through used by MPT Fusion SAS HBAs and the "smp_portal" sysfs attribute pass through used by at least one aic94xx based Linux driver.

This version adds the smp_phy_test and smp_discover_list utilities. All SMP functions defined in SAS-1 and SAS-1.1 are now supported with some support to SAS-2 extensions (see the COVERAGE file). See the CHANGELOG and README files for more information.

One new feature, borrowed from Luben Tuikov's expander_conf.c, is to loop over consecutive phys in smp_discover to produce a summary of what is attached to an expander:

# smp_discover --multiple --brief
Device <500605b000000af0>, expander (only connected phys shown):
  phy   2:S:attached:[5000c500005208ee:01  t(SSP)]  3 Gbps
